I did a modification of the recipe below and used unbleached flour for the source of the wheat and the use of 6 Row for more enzymes/husks.
I did NOT use rice hulls, did a batch sparging and it ran pretty clear.
There were two keys for me.
1. Cut the top of the grain bed periodically to keep the wort flowing.
2. Keep about 2 1/2 feet of head pressure (actually vacuum in this case) between the mash tun and the grant. (I used a 3/8" id vinal tube to drain the mash tun. keep the opening of the tube under the collected wort)
IMHO, the column of wort creating high pressure differential between the outlet and the reservoir of wort above the grain bed. And before you ask, no the grain bed did not get overly compacted. The batch size was 5 Gallons.

I've yet to bottle the result, I've tasted the un-carbonated product and its good.
